The speed of the reaction and ways to increase it

The speed of reaction is one of the main qualities of any living organism. At the same time, it is very important that the response to external irritant factors is instantaneous, since among them there can be not only dangerous, but even deadly ones.

From the immediate onset of the influence of the stimulus to the moment of the reaction, there must always be some time, during which the response action of the muscles turns on, for the speed of which the reaction rate already corresponds. The time of such a delay is called the "latent response time". It is determined by the metabolic rate and is characterized by an individual characteristic of a particular organism. Such a latent time can not train, because it is simply physiologically impossible to accelerate the transmission of nerve impulses.

The average speed of a person's reaction to a visual signal is only about a quarter of a second. This indicator depends on the work of the nervous system. An example is the reaction of a person to a sufficiently strong irritation, which can be life threatening. When withdrawing a hand from a hot stove, the brain does not take any part. The signal from the receptor through the nerve fiber enters the spinal cord and then directly to the muscle, passing along the three nerve cells: intercalary neuron, sensory neuron and motor neuron. The reaction rate in the form of a nerve impulse in this case is measured by a figure of several tens of meters per second.

First, a person pulls back his hand, and only then does he get pain. This is due to the lower signal speed that passes from the pain receptors to the brain through nerve fibers of a slightly different type than those listed above.

Checking the speed of the reaction of a person to a stone flying into it is as follows: with the help of the eye, a signal is transmitted about movement not only to the brain where it is to be treated, but also along certain nerve pathways to the muscles, which facilitates rapid reaction and withdrawal in Side.

Thanks to the achievements of today's medicine, scientists have managed to prove that a person's reaction speed can increase. Studies were conducted on football players, hockey players and tennis players, who were trained to concentrate their attention simultaneously on several sites. The results showed that after training, the ability to simultaneously "absorb" more information with its productive use increased by 53%.

The reaction speed is one of the main qualities that can determine the result of the fight in the ring. Indeed, it is precisely from the correctness and speed of response to the actions of the enemy that often depends not only on winning in battle, but also on the life and health of the fighters themselves.

To improve the response to stimuli that precede a dangerous action, one can, for example, react not to the shock itself, but to the initial preparation for it. After all, the enemy, before striking, always looks at the target, strains his muscles, changes his pose, etc. It is only necessary to work out some reflex and put a response to the new stimulus in the subconscious.
